Ubuntu Server 7.10 Used the "Postfix Spam Filter using Ubuntu Dapper, MailScanner, SpamAssassin, Razor, Pyzor, DCC and ClamAV " how to. I Got mailflow working and was even able to watch the mail.log entries by typing tal -f /var/log/mail.log. I could see the messages being scanned. Then I went to install the Mailscanner-MRTG. Typed apt-get install mrtg apache2 snmp snmpd libsnmp4.2 Wan not ablle to find the package libsnmp4.2. Used atpitude instead and it still could not find it but the install proceeded. Got to the reboot and here is the reboot message I get Starting Mailscanner... Starting MailScanner...
